T5 Smart Wi-Fi Thermostat

Works great - our second one in the home - this one is for the upstairs. A little mechanical & wiring know how (and snapping a pic of the back side of the old t-stat) made the process go fast. Once connected to the app, programming was a breeze. Like the geofencing option too - sets the temp control up or down once you get to a certain distance from the house. Display is great too - very clear and easy to read. 100% recommend this if you need a simple wi-fi enabled upgrade for a good price.

What can I say, it is a thermostat and it looks nice, I bought it for these reasons. I bought it in April of 2023 right after I had a leak repaired and the old thermostat looked very dated in a freshly painted room.It installed very easily and It really does look nice and new in the room. Once up I was pretty happy with it. I set a schedule and that's where the enjoyment stopped. As time went on I began to wonder if I had a leak or something, I had one in the past after all. It would not cool, and the temperature in the house would rise. I'd set it to 71 but the temp would slide degree by degree to 77 (which is what it was scheduled to hit at 11pm) and stay there for the night. Suddenly waking up freezing in the morning. The pillows in the bedroom were muggy and damp intermittently. Some days we'd sit at 77 degrees for no reason. The heat pump is running near 24/7 trying to cool the house....Luckily I am pretty DIY and troubleshooting for hobby so I bought gauges to monitor my unit and learned what Superheat and subcooling are. I determined that I don't have a leak! So what is it? I have an energy saver cycling box from the power company, I have that taken off, it takes a few weeks for them to do it. but my problem persists! I'm going mad, inject dye to search for leaks? I change filters, etc etc. anything i can. I'm debating draining the unit, perhaps the repair guy put in too much or incompatible oil!I begin to suspect the thermostat, all the internet says it couldn't be the thermostat, no no It could never.. But I say I say you know what let's reset the thing and strip away features. So I did, Reset it, turned off scheduling, wifi, and anything else "smart", got into the special menu and found "adaptive recovery" looked it up and determined this and scheduling were my problems! Because I wanted 72 from 8am to 5pm but the 77 at 11pm. The stupid "smart" algorithm thought that meant I want to be 72 in 8am and for the rest of the day slowly drift to 77 by 11pm and then freeze us half to death at 5am to be 72 again by 8am. If I set my schedule to all 72 degrees it will never leave 72 even on a "hold". I assume because of crap programming that adaptive recovery does not take into account the "hold" or manual input/changes which is bullcrap.I decided to see how badly programmed this algorithm was. I put a schedule on with crazy temperatures like 50F at 8am and 90f at 5am or something. The stupid thing would actually turn the HEAT ON to after 8am so that it be 90F by 11pm even though the cool setting was set to be 50F at that time. what a dumb program. Heating when it should be cooling!I was smart enough to figure this out and disable these features, I won't even use the schedule now Im too afraid too Which is same because I really wanted to let the AC drift off temp at night but its not worth it to trigger the "smart" alogrhtium's stupidity which seems to have the ability to override your manual temperature settings even without being turned on. I see no where to fully disable this "smart" features.I feel bad for anyone that calls HVAC specialists to try to fix these issues and they get talked into the a whole new system because of some programmers' poor programming skills.

Easy to use and setup. The Wi-Fi conncetion works well, and I love being able to control the temperature from my phone. The display is clear and easy to read, and the temperature control is accurate. Very well recommend it.

Honeywell can go suck start a shotgun.I'll admit, the first step was on me. In the 600 character title, I didn't catch the "C wire required" at the end. Nonetheless, a green (fan controller) wire will work as well. But, holy hell this is the worst experience I've ever had with a thermostat.The setup process is beyond complicated, and that's coming from a guy who works in IT. "Download the app" - okay, which app? There's several that it says. I think in the manual it says you need the Lyric app. Well, the Lyric app doesn't exist. There's honeywell apps, and I downloaded 4 Honeywell apps before I learned it's a RESIDEO app that I needed, of which there's THREE of those apps as well. Once I was able to find the right app, it started guiding me through the process - but it only took about 2 minutes for it to fail on setup. Plug it into the wall, select App Setup, make sure it says bLE at the top. Done. Your phone should start looking for the thermostat...... but it can't find it. "Hold it closer!" - it's 2 inches away from the thermostat.As it turns out, you need to select "NO" on the bLE. It'll then tell you to set your phone to airplane mode, turn on wifi, and find your thermostat's wifi - connect to that, set it up, and then you'll start being on your way. Everything checks out until it comes time for your thermostat to join the wifi. That's when it'll fail again. It does require to be on a 2.4Ghz band, which I've already got a split network set up in my place for that. Still, it refuses to join - it'll begin trying to connect to the wifi, and it will boot my device of the thermostat's wifi. The *APP* will then ask for me to connect to the thermostat's wifi again, in which it'll refuse to let my device connect back to it.After trying the process over and over and over, I gave up and tried setting it up without the app. From here, it managed to nearly get onto the WiFi... I mean, it did - my wifi notified me that a new device had joined my network. However, now the thermostat was telling me I needed to register it in order for the remote access to work.Fine. Whatever. I go online to see how I'm supposed to register it, and... well, you can't. For the T5, you need to register it through the app. The app that doesn't work. The app that fails on setup.This thing is almost entirely backwards in it's setup process. Everything will fight you every step of the way. This thing is far from "user friendly" or intuitive. Get something else. Get an Ecobee. Get a Nest. Teach your infant child on how to adjust your current thermostat. Anything is better than this.

I would save your money on the new ones and just buy the refurbished models in these that they sell on Amazon. They would likely work just as well. I got the new ones for 75 on prime day. The refurbished ones sell for 60 all the time.They work for the most part. Setup is fairly simple. GeoFencing seems to break functionality for me, so I turned it off and just use alexa and the app to tell it to change temps when I leave the house.The screen is nice and I like that you can adjust the brightness from you phone. I don't like that it goes down to just the temp reading in the house which is the sleep mode. I would prefer it just leave all the information up all the time so I can read it when I walk by without having to touch it.Make sure you know exactly what kind of heating unit you have. I just bought a new build and they told me I had electric heat without a heat pump. They told me wrong, and I do have heat pumps. If you put the heating and cooling information in the wrong during the app set up it will not call for the correct air. Make sure you double check this before installing, as I learned the hard way, and had to reset the thermostats and start all overI can't speak on wiring it up as I didn't need to that since I had the Honey Well pro series thermostats(Non-WiFi) in my house from the build. It was a plug and play method for me, which is why I bought these. Saved me a lot of time.Over all I like them, but I do feel like they take forever to register that the room is actually to temp and causes my AC to run a little longer. I'll see how my electric bill compares to the month before without these installed and update my review. Also wish they didn't go into sleep mode and instead showed all the information on the screen all the time. Also wish the GeoFencing feature worked better, but this could be more of an issue with my phone not registering in the area correctly. As I said, take a chance on the the refurbished ones it will save you some money and probably work just as well.

I had to connect my C wire to make this work. I love this unit. As soon as I change the temperature on my phone app I hear the unit turn on. It looks good and has a touchscreen. It's easy to use. There's no monthly fee and I can change the temperature inside my home while I'm at work.

Easy to installWorks as describedWould againNice easy to read

I bought this thermostat to replace the T6 ProSeries from Honeywell, so that I wouldn't have to run up and down the stairs every time I wanted to turn off the heat. Since you need a PhD in order to set the schedule on the T6/T5 models, I wanted the flexibility of setting up routines in Alexa to have it turn on at certain times and run for only a few hours instead of constantly. Because the Honeywell T6 is basically a non-wifi version of the T5, installation was as simple as pulling off the T6 and slapping on the T5. Pretty much plug and play. HOWEVER, if you do not identify your proper AC/heating in the app setup, you will experience non-stop frustration!! Initially when I tried to operate the T5, I had my settings set to Conventional Air, Cooling stages=1, Heating Stages=1. This just resulted in only turning on the furnace fan and not the outside unit. During my troubleshooting, I noticed the O/B wire which let me know that I had to configure the heat pump in my setup. So now the new app configuration is Heat Pump (instead of Conventional Air), Reverse Valve=O (most common), Cooling stage=1, and Heating stage=1. If you are pushing out cold air instead of warm air from your system or vice versa, then that means that your Reverse valve is energizing on the wrong setting. Just go back into the app and change the setting. Other than that, I can't say enough nice things about my new thermostat. Now I can lay in the comfort of my bed and tell Alexa to change the temperature or shut off the system.

Funciona perfectamente y muy sencillo de usar. Muy buen producto

Easy to set up and control from anywhere when you use the app. Excellent product and great price.

I bought two pieces and both didn’t work! I tried returning them and didn’t help

The time keep resetting to different time zone. Tried several time but it keep resetting

The unit is sturdy feeling, and has all the features you need without the excess garbage. Use the app to “ set it and forget it”. You can’t beat a Honeywell Thermostat.
